Perfect number is a number which is equal to sum of its divisor. For eg,divisors of 6 are 1,2 and 3. The sum of these divisors is 6. So 6 is called as perfect number

Write the Code in different languages in the comments, we will add this program in the comments section later

    #include
    int main(){
    int n1,n2,lcm,sum=0;
    printf(“enter n1”);
    scanf(“%d”,&n1);
    printf(“factors are”);
    for(int i=1;i<n1;i++){
    if(n1%i==0){
    lcm=i;
    printf(" %d\n",lcm);
    sum=sum+lcm;

    }
    }
    if(sum==n1){
    printf("number is perfect number %d",sum);
    }
    else{
    printf("number is not perfect number");
